How can Atom Publishing Protocol GET be used to locate entry(s) of interest in an entry collection?
For example, Client A posts an ad (atom entry specifying ad details via APP POST). Client B wants to update the ad entry posted by Client A. Client B knows some context about the ad, such as product ID and the entry collection URL. How does Client B obtain the ad atom entry posted by Client A (thus obtaining the edit-url). How can Client B query a entry collection via APP? I am thinking along the lines of a GET with search parameters. The result would be an atom feed containing 0 or more entries that matched the search criteria. Is there an example that exists that does this today? Thanks, Nathan
